4. Known Issues

Trend Micro Apex Central™ as a Service

There are no known issues for this Hotfix release.

Trend Micro Apex One™ as a Service

Known issues in this release:

Known issue 1

Security Agent consoles running build 13.95 display an incorrect policy name. To resolve this issue, upgrade the Security Agent to 14.0. After the Security Agent contacts the server, the policy name displays correctly.

Known issue 2

Off-premises and Security Agents in Independent mode cannot update the Certified Safe Software Pattern from external update sources.

Known issue 3

Coexist mode Security Agents on endpoints with Windows Defender may experience installation issues or be unable to upload data to the Apex One server due to a file locking issue. To resolve this issue, add Endpoint Sensor (ESEServiceShell.exe and ESClient.exe) in the exclusions list of Windows Defender to prevent the locking issue.

Known issue 4

After copying a file to a remote server using a relative path as the source, Apex One is unable to translate the relative path into the full system directory.

Known issue 5

The quality of RCA analysis chain image files is reduced when viewing the files using Windows 10 Photo Viewer.

Known issue 6

When attempting to start a Historical Investigation from the Attack Discovery Detections widget that includes Registry value name or Registry value data criteria, the Historical Investigation displays an error message if the length of the Registry value name exceeds 260 characters or the Registry value data exceeds 64 characters.

Known issue 7

After updating the Attack Discovery Pattern file (tmesadp.ptn) on Security Agents, a database schema error may occur that causes the Endpoint Sensor feature to continuously report the same detections to the server during each synchronization. This causes duplicate records to display on the Apex Central server.

Known issue 8

Root Cause Analysis email attachment results may also include temporary files created when the user saved the file.

Known issue 9

The number of matched endpoints that display on a Root Cause Analysis chain may appear to be greater than the total if the Security Agent on an endpoint was uninstalled or no longer reports to the same managing server.

Known issue 10

The Endpoint Sensor service may have high memory usage.

Known issue 11

The Endpoint Sensor may have high peak CPU usage occasionally.

Known issue 12

Endpoint Sensor has CPU peak during Windows Update phase.

Known issue 13

The user or account name in ADE detection may be empty.

Known issue 14

The EC module may stop responding while handling NULL data which may cause the ESEService and ADE functionality to behave abnormally.

Known issue 15 
In rare conditions, ESEService stops responding while unloading.

Trend Micro Apex One™ (Mac) as a Service

Known issues in this release:

Known issue 1

After enabling the Scan Time Machine option for Manual Scan and Scheduled Scan, Apex One (Mac) cannot perform any actions (clean, quarantine, or delete) on detected malware threats due to a permission limitation in Mac OS. Configured scan actions are displayed as unsuccessful in the product logs.

Known issue 2

When performing a historical investigation on Apex One (Mac) endpoints, the system replaces a slash (/) with a colon (:) in file names, preventing users from searching for file names that contain backslashes in investigation results.

To resolve this issue, use a colon (:) to search for the files.
